Just sounds like soundbite bollox to me and a way of getting the lower class under control with fear of further taxation and to not get caught cheating. Reality is they cant implement this without throwing a shitload of money at extra manpower for a small gain and let's be honest, there are other services that could really do with that injection of cash.
I myself rent out spaces on my driveway but i have to stay within the £1000 limit as recommended by the parking app to avoid paying tax. As soon as i get close to the limit i mark the spaces as unavailable.
Until i receive notification from the app that tax will be changing i will continue to do so and hold them culpable if i get fucked over.
